I'm trying to educate myself so please excuse my ignorance. I am trying to project my Desk top to my TV with an HDMI cable. I cannot get my desk top to detect a second display. THe HDMI cable works, i am on the correct input and I have tried select the extend mode and it's still not working. I have looked online for several hours working through solution and still nothing. I know I'm missing something obvious. I am using windows 10 and have an Intel Graphics HD 4600 if that helps. Thank you in advance for any help i receive.
